\subsection{Scientific Perimeter of the project}  \begin{itemize}  \item On parle de DM, de BAO, de photo-z.  \end{itemize}  - Photo-z : Marc Moniez  * plan de travail discuté au sein du groupe de travail LSST-photo-z  * première note interne ecrite  - Long terme : participation au DESC = BAO As we mention above, the Dark Matter enigma has been a scientific topic present in Montpellier since the early 2000. For instance, members of the group have lead several analyses of Fermi data in Dark Matter Indirect searches, especially in the context of dwarf spheroidal galaxies. Optical observations of galaxy clusters have also lead members of the group to investigate large-scale structures and comparison with what the Cold Dark Matter (CDM) paradigm predicts. LSST will both likely discover new dwarf spheroidal galaxies, for which the LUPM gourp will be ideally positioned to use archival Fermi data, and make critical observations to understand the large scale structure of this Dark Matter component. One such observable is the Baryon Acoustic Oscillation, a key probe for the CDM paradigm in particular and the cosmological fit in general.  While the group's interests may well evolve and expand in the 6 years or so that separates us from LSST science operations, it is worth mentioning that the shorter terms scientific interests just outlined will be supported by a more concrete activity focused on LSST photometry, especially with respect to the opportunity to use Gaia in the photometric calibration pipeline.
